• Asymmetric Digital Subscriber Line (ADSL): ADSL broadband connection is available in nearly all homes in Cardiff and is one of the cheapest options. However, many customers choose fibre optic options over ADSL due to relatively higher speeds.
• Fibre-to-the-cabinet (FTTC): FTTC or part-fibre broadband is popular for its speed and reliability. However, its speed depends significantly on the distance from your property to the street cabinet and the quality of the copper wires covering the distance between these.
• Fibre-to-the-premices (FTTP): FTTP or full-fibre broadband is also widely available in Wales at speeds ranging from 100 to over 1,000Mbps. In fact, more than 50 percent of households in Cardiff support FTTP broadband connections. One of the main perks of FTTP broadband is its speed and stability.

• Broadband and phone: This type of package gives you broadband internet and phone coverage. Broadband and phone packages usually come with data and phone minutes. While it’s usually more expensive than broadband-only plans, these deals can be cost-effective. Broadband and phone packages also offer greater convenience since both services come from the same provider.

What factors should you consider before choosing the best broadband provider in Cardiff?

Choosing the best broadband deal in Cardiff can be arduous if you don’t know what to look for. So, here are some things to keep in mind when looking at internet providers in the capital of Wales:

• Speed: Speed is easily one of the most essential factors when choosing a broadband provider. Everyone wants a fast internet connection. Broadband providers offer different speeds depending on the part of Cardiff you live and the type of broadband you’re using. The speed you get will also depend on your budget since broadband providers offer different internet packages at varying speeds.
• Price: Broadband internet is available in Cardiff at different price points. Superfast internet tends to be more expensive than standard broadband services. We recommend picking a provider with packages that suit your budget and internet usage needs.
• Reputation: It’s essential to consider the reputation of any broadband provider you pick. You want an internet provider known for offering excellent services in your area. We recommend checking online reviews and forums like Reddit to gauge how other users rate your preferred broadband provider.
• Coverage/availability: Is your preferred broadband provider available in your neighbourhood? How comprehensive is their coverage in Cardiff and throughout Wales? Choose a company with extensive local coverage for the best speeds and most reliable broadband connection.
• Contract length: Internet service providers typically offer short and long-term contracts. Most contracts are between 12 to 24 months. While long-term agreements are more cost-effective, some broadband providers have cancellation fees you must pay if you choose to leave the contract before it elapses.
• Customer service: It’s crucial to assess the customer service of your preferred broadband provider. Is it easy for customers to get assistance when connectivity issues arise? You want a provider you can reach at any time with whatever problem you may be experiencing so you can be sure of getting the help you need.

What broadband speeds can you expect in Cardiff?

Cardiff has relatively fast broadband compared to other parts of Wales. Cardiff's average broadband speed has increased in the last few years, from 16 Mbps in 2018 to an average of 108 Mbps in 2024. Broadband speeds above 100 Mbps are ideal for gaming and streaming. Although speeds have increased rapidly in the last few years, Cardiff is still catching up to other major cities in the UK.

It's worth noting that these average speeds may vary considerably depending on your specific location and connection type. For example, areas with full-fibre (FTTP) coverage may benefit from much higher speeds, potentially at 1 Gbps or more. On the other hand, some areas still relying on ADSL might see lower speeds. If you want a more accurate picture of speeds at a specific address, using a postcode checker or contacting local providers is best.
